First post - Nothing saves anymore!

I wanna say hi and thanks to the whole community for everything that changed the world of game emulation.

I have this arcade cabinet that my friend made years ago and I’m getting familiar with the basics of Retroarch but…

Recently, I noticed that when I’m done playing and do “Shutdown System”, nothing I did is remembered the next time I reboot the whole thing, which I did for years without any problem. Not only save states but also roms I deleted, configs I changed, Last Played games, inputs, nothing!

I tried to expand the file system and few other things but whatever I do, It’s like the Groundhog Day!

Thanks for your help and Happy Holidays!
